OWN: Oprah Winfrey Network(NEW YORK) -- Lindsay Lohan has vowed to change her partying ways. However, in a clip from her OWN TV series, the actress admitted that steering clear of substances isn't always easy.

"I'm sober but I've been very close," she said. "It has come very close and it's really scary."

Lohan, 27, had been working with Michael Cormier, a sobriety coach, to make sure she stayed on track. However, he made it clear that he didn't want to become "the sobriety crutch," and returned home to L.A. after Lohan settled into her New York home.

"It was important that Michael was here because I have to be somewhat accountable to someone that I respect and I know knows better," she said. "I think a lot of the reason that I've slacked on [Alcoholics Anonymous] meetings because I've had Michael here because I feel like if he's around, I don't have to go to a meeting."

In a separate interview, Cormier was hesitant to say that Lohan was still sober, saying only that he didn't have "hard evidence" that she's not.

For Lohan, it's still a struggle, she said.

"I do love the nightlife and hearing loud music and dancing and laughing and having fun and that's a great feeling," she said. "But it's knowing when you're able to be in that situation and not feel uncomfortable when someone has a drink around and stuff like that."
